本SAE航空航天标准(AS)规定了钛、CRES和铝管上的轴向锻造钛配件的要求，这些配件具有无扩口可分离配件端，用于最大工作压力高达5080 psig(35000 kPa)的航空航天流体系统中。钛管和CRES管的工作温度范围为-65至+275°F（-54至+135°C），铝回流系统管的工作温度范围为-65至+225°F（-54至+107°C）。 本规范涵盖了常见的5080 psi压力钛配件，该配件可用于高达5080 psi的工作压力范围，具有不同的管道材料和管道壁厚，并根据AS5959用相同的工具组装。无扩口接头工作压力基于接头螺距。超细螺距用于5080 psi的工作压力，细螺距用于3000 psi及以下的工作压力。 表14 显示适用的航空配件零件号标准和管道材料以及工作压力。

This SAE Aerospace Standard (AS) establishes the requirements for axially swaged titanium fittings on titanium, CRES, and aluminum tubing with flareless separable fitting ends for use in hydraulic supply and return aerospace fluid systems up to operating pressure of 5080 psig (35000 kPa) maximum. The operating temperature range for titanium tubing and CRES tubing is -65 to +275 °F (-54 to +135 °C) and the operating temperature range for aluminum return system tubing is -65 to +225 °F (-54 to +107 °C). This specification covers a common 5080 psi pressure titanium fitting that may be used for a range of operating pressures up to 5080 psi with different tubing materials and tubing wall thicknesses and is assembled with the same tooling in accordance with AS5959. The flareless fitting operating pressure is based on the fitting thread pitch. Extra fine pitch is used for 5080 psi operating pressure and fine pitch for operating pressures 3000 psi and less. Table 14 shows applicable aerospace fitting part number standard and tubing materials and operating pressures.
